  • Patent number: 11343951
    Abstract: The object is to provide a substrate processing machine facilitating checking the operation of a device in the interior of a housing from the exterior of the housing. The substrate processing machine includes a base and a module, disposed on the base, and has a device configured to perform a predetermined operation contributing to the production of a substrate. The module can be switched between a fabrication position where the substrate is produced and an offset position that deviates from the production position relative to the base. The device can operate in the production position and the offset position. The operation speed of the device in the offset position is slower than the operation speed of the device to in the production position.

  • Patent number: 11147201
    Abstract: In the component mounting device, a control device includes a model data storage section for storing model data related to a component, an error determining section for determining whether a processing error has occurred, and a confirmation-necessity storage section for storing whether confirmation of the validity of the model data is necessary when the processing error has occurred in a series of processes performed based on each piece of model data stored in the model data storage section. When it is determined that a processing error has occurred, the control device temporarily suspends the operation of the component transfer device when the model data, related to the target component held by the component transfer device, stored in the confirmation-necessity storage section indicates that confirmation is necessary, but continues the operation of the component transfer device when the model data stored in the confirmation-necessity storage section indicates that confirmation is unnecessary.

  • Patent number: 10966361
    Abstract: A dedicated correction value related to the mounting position of an upper surface recognition component with a characteristic section on an upper surface thereof is memorized in correction value folder 43a of an HDD, and when performing mounting work of mounting the upper surface recognition component on a board, a position deviation amount of the characteristic section is acquired based on an image of the upper surface of the upper surface recognition component captured by a mark camera, and the component is mounted at the mounting position based on the acquired position deviation amount and the dedicated correction value. Accordingly, it is possible to mount the specific component at a corrected mounting position such that the position of the characteristic section is appropriate, thereby improving mounting accuracy for the upper surface recognition component.

  • Patent number: 10919711
    Abstract: A component mounting device including a component mounting head that mounts a component on a board by using a first raising and lowering device and a second raising and lowering device. The second raising and lowering device causes an engaging member to engage with an engaged member of a suction nozzle, and by further advancing the engaging member causes the suction nozzle to advance against a biasing force of biasing member. Further, a control device is configured to cause the engaging member to move in the advancing direction by using the actuator of the second raising and lowering device and detect an engaging position in a vertical direction at which engaging member engages with engaged member.

  • Patent number: 10716250
    Abstract: A component mounting apparatus is provided with a controller that controls a mounting head. The mounting head is provided with a nozzle holder, a nozzle that is elastically supported to be movable up and down with respect to the nozzle holder, a flange that is provided at a position that is offset from the central axis of the nozzle, and a second engaging section that is able to move the nozzle downward by engaging with the flange and pressing down the flange against the elastic force of a nozzle spring. The controller measures in advance the deviation amount of the tip position of the nozzle between before and after the second engaging section moves the nozzle downward and controls the mounting head so as to suck the component and mount the component on the board taking the deviation amount into account.
